OF PHILADELPHIA, PENN- SWlVEL-TRUCK FOR ELECTRlCALLY-PROPELLED CARS Specification of Letters Patent.

Application filed June 1,1906. Serial No. 319,667.

To a, whom it n'my concern:

Be it known that I, DANIEL M. PFAUTZ, a citizen of the United States, residing at Germantown, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Swivel- Trucks for Electrically-Propelled Cars, of which the following is a specification.

My invention has relation. to that class of electrically-propelled cars adapted to be suspended from an elevated-railway structure; and in such connection it relates to a swiveltruck adapted to travel along on said structure and support'the car in a suspended condition.

The principal objects of my invention are, first, to provide a simple and efficient swiveltruck for elevated-railway structures with suspended cars second, to rovide a swiveltruck with two superposed disks movably connected at their periphery with each other and at their vertical central axis, the lower disk supporting the car and the upper disk supporting the lower disk and car and the driving-wheels and motor; and,

united at their lower ends and with mechanism adapted to bring one or the other of the said trolleys into operative position as reuired.

The nature and scope of my present invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which v Figure 1 is a side elevational view of a car and a portion of the superstructure of an elevated-rail way system, showing in side eleva tion swivel-trucks supporting the car and a double trolley and means for operating the same, embodying features of my present invention. Fig. 2 is an end elevational view of "a car and a portion of the superstructure,

showing in end elevation a swivel-truck supporting the car. Fig. -3 is a top plan view of the swivel-truck of the car. Fig. 4 is a front elevational view thereof, partly sectioned; 5 is a vertical sectional view of the swivel'mechanism-of the truck, the motor, axles, and wheels thereof being removed.

Referring to the drawings,a represents a colunm supporting a, cross-girder a, to which are suitab y secured longitudinal girders b and b To the lower inner flanges b and b of the longitudinal girders b and b are secured rails b and I)", over which the Wheels d and d of the swivel-truck of a car (1 suspended therefrom travels, as will be hereinafter more fully explained. To the cross-' girder a is secured a bracket c carrying a hood 0, within which theelectric trolleywire a is located. The car 61, suspended from the truck f, is provided with rear and front platforms (1 and d and dashboards d and d, and within the same is arranged a metal framework, as indicated in dotted lines in Fig. 1. The axles d and d of the swiveltruck f are carried by brackets f and f suit ably secured to the under side of a disk f which by means brackets disk f and bolt f 7 are connected with the metal framework f of the carbody d, as shown in Fig. 5 of the drawings. Below the disk f and centered on the kingpin f 4 is arranged a second disk f which by means of the bolts f 7 is rigidly secured to the metal framework f 5 of the car (1 and rests directly upon the roof (1 thereof. To the disks f are secured, preferably, the four brackets f each carrying at the upper free end a roller f engaging the upper disk f 3 at or near the periphery thereof. rollers f and the king-pin permit a certain movement of the car (i and disk f 6 in respect to the upper disk f which is supported by the axles d and d of the truck f and to sustain the weight of the car cl. connection between the upper disk f and lower disk f 6 permits the truck f of the car to take tosharp curves with ease, in which instance the rollers f? f will readily adjust the position occupied by the lower disk f and position occupied by the n truck On the roof (Z -0 per disk f 3 and the car d is loof a king pin or bolt f and These four brackets f,-

Having thus described the nature and objects of my invention, what I claim as new,

and desire to secure by Letters Patent, is

. 1. In an elevated-railway system, a car having on its roof a swivel-truck, comprising two superposed disks, theu per' disk adapted to carry the axles and living-wheels of the car, and the lower disk adapted to carry the car and having brackets surrounding the upper disk and carrying rollers engaging said. upper disk, said brackets: and rollers in con' junction with said upper disk adapted; to-support the lower disk and car, substantially as and for thepu-rposes described-i.

2. In an elevated-railway system, a. car having on its-roof a swivel-truck, comprising two superposed disks, the u ed to carry the axles and 'rlvingewheels of the car, the lower disk adapted tocarry the car and brackets surrounding the upiperidisk and. carrying rollers engaging said upper disk a king-pin assingn rough the w and bdthof said. ks, said kingepin, brackets and rollers in conjunction with saidper disk adapt 9 upper disk adapted to support the lower disk and car, substantially as and for the purposes 7 ed to carry the axles, driving-wheels and motor of the car, and the lower disk havin bolts and brackets-carrying rollers, said bolts adapted to connect said lower disk with said car, and said brackets adapted to surround the upper disk and engage the same with its rollers, a king-pin assing through the car and said disks, said king-pin, brackets and rollers inv conjunction with said u per disk and the bolts of the lower disk a apted' to support said lower disk and car, substantially as and for the pu oses described.v
